i am designing an experimental platform to test some 3D printed gears that i am designing. i want to test the durability and what i am looking for is a way to make them wear out fast. i will basically put 2 or 3 gears in series and form a gear train, then run them until they "fail", i am basically cehcing the vibration emitted by each gear, and i currently do it by placing an accelerometer above the shaft supporting the gear itself (above the shaft supporting bearing to be precise)
however the gears reach a point where the vibration increases no more just after running for 15 min.
Any advice on what kind of way to install the accelerometers or other sensors? Or if i should change my DC motor, runs at 24V at 2000RPM but heating up too fast so i have to stop every 10 15 min of run.
